lUNiTEn STATES W'ILLIAM A. BOYDEN, OF JERSEY CITY, NEW JERSEY, ASSIGNORTO THE MGNAB & HARLIN MANUFACTURING COMPANY, OF NEV YORK, N. Y.

SIGHT-FEED LUBRICATOR.

To all whom it may concern:

Be it known that I, WILLIAM A. BOYDEN, a citizen of the United States,residing at'Jersey City, in the State of New Jersey, have inventedcertain new and useful Improvements in Sight-Feed Lubricators, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

My invention relates to improvements in IO sight feed lubricators; andthe object of my improvements are to provide means by which the pressureon the oil is equalized byadmitting steam thereon, by placing thesight-feed where it can be conveniently seen and the I 5 mechanismreadily controlled which regulates the lubricator; also, to so constructthe several parts that they are not liable to get out of order or clogin working. I attain these objects by the mechanism and construction asshown in the accompanying drawings, in which- Figure l is a sideelevation; Fig. 2, a vertical section; Fig. 3, as arranged to lubricateboth valves and cylinders of a locomotive.

Similar letters refer to similar parts throughout the several views.

The oil-chamber A is supported on the central column, B, and is providedwith asteampipe, I), which delivers the steam above the oil, and whichprojects up and into a central hollow cap, and a regulating-valve, 0,whose port is in a position that any sediment that may be in the oilwill pass downward, and by the exit-port c settle in the bottom of thechamber A, thereby preventing any clogging of the 5 exit-port, which inworking is only slightly opened and, as heretofore, liable to receivethe sediment, causing great annoyance by an irregular or the stoppage ofthe flow, and which, when once set, it is absolutely necessary that itshould continue to discharge regularly; otherwise the parts to belubricated become heated and cut.

The sight C is placed laterally tothe column 13 and below the chamber A,and consists of a glass tube, 0, provided with a driptube, d, whichleads from the exit-port a, suitable connections, 0 and c, and the wayf,which connect with the central column, B.

ECIPICATION forming part of Letters Patent No. 305,281, dated September16, 1884.

Application filed June 28, 1884.

(No model.)

To the column Bis attached avalve, G,which regulates the passage of thesteam and a cutofr" when not in use.

As shown in Fig. 3, the cup is arranged to lubricate both valves andcylinders of a locomotive, and is attached to the boiler D, with anintervening valve, 9, and provided with a double set of sight-feeds, Cand 0, one leading to each steanrchest by the pipes g and 9 providedwith valves h and h, whereby either or both the valves or cylinders maybe oiled from a single chamber.

In operating my invent-ion, before filling the cup, close both valves,remove the cover, and pour in the oil. Replace the cover and open thelower valve wide; then regulate the flow of oil by opening the uppervalve. The feed can be regulated so as to draw ed the condensed steamwith the oil, so that when all the oil is used there is noeondensationin the cup, and it is ready to be refilled Having fullydescribed my invention,what I claim, and wish to secure by LettersPatent,

1. The combination of a central steam-port opening above the oil, and ahorizontal exitport below the oil, with a sight-feed, for the purpose asherein set forth.

2. The combination, with a central steampipe, 7), proj ecting into thecap a, of the central cap, a, the horizontal exit-port c, and thesight-fecd C.

3. The oil-cup A, combined with the central hollow supporting-column, B,internal upright steam-pipe, 1), lower oil-discharge opening, 0, valve0, downward-extending drip-pipe (Z, sight-tube C, and anoutward-extending sep- 8 5 arate oil-discharge pipe, 9, having anindependent valve, 71, substanti all y as herein show u and described.

In testimony whereof I atlix my signature in presence of two witnesses.
